Product Description

Used in drag racing, street performance, autocross, road race and street rod applications, Proma Star shocks are the best for hard-core performance.

QA1’s Proma Star shocks are available in both double and single adjustable options. Made with a lightweight aluminum body, Proma Star shocks are ride height adjustable and even include the spring mounting hardware. As with all QA1 aluminum shocks, Proma Stars are 100% dyno tested and serialized.

With QA1’s Proma Star Single Adjustable coil-over shock, you can easily adjust your compression and rebound valving and get the hard-core performance you need. One knob allows you to choose from 18 valving options that adjust both compression and rebound valving simultaneously, allowing total suspension control in one easy-to-reach location.
